The Stovebolt Site Forums The Shop Area The Electrical Bay 66 turn signals

when I bought the truck (66 C10) I found the turn signal arm that sticks out of the column laying on the dash. I have not taken the steering wheel off to look but I am hoping someone can give me an idea of what is broken inside. Is it the turn signal switch, the turn signal switch cam or the turn signal switch cancellor. Im guessing what ever is broken is what the turnsignal arm is screwed into. I was hoping someone else might know so I didnt have the column torn apart while I waited on parts. Thanks.

IIRC the turn signal arm is held in the canceling cam with a sheet metal screw. The canceling cams are replaceable and you should be able to find one of the repo dealers, The filling station, Classic Chevy, LMC, etc., check the links here. The canceling cam is what usually goes bad and doesn't turn the signal off. You will have to pull the steering wheel to replace it.

Complete turn signal assemblies, including wiring harness and factory plugs, as well as, rebuild kits, are available from the following aftermarket truck suppliers:

www.bowtiebits.com
www.lmctruck.com
www.classicparts.com
www.oldchevytrucks.com

and many others.

I have also found them used on eBay for significantly less money, however you run the risk of a fragile unit and failure in the same way your's has failed, when buying used.

In any case, the repair or replacement of this assembly is very common and a relatively easy process. You will need to remove the steering wheel (puller and 3/4" socket required), in order to do the repair.

When doing this repair, I always apply di-electric grease to all contact areas during reassembly. This will ensure good, smooth operation of the newly installed unit.

Good luck with your project and let us know how things turn out.

Thanks so much for the pointers. I probably will attempt the repair later this week. I appreciate the information on the die electric grease. I will let you know how it goes.
